Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have just converted my XP box across to redhat 9, I have managed to install just about everything a productive person needs to have installed, Digital Camera,USB MAss Storage (Not 2.0 YET :-()Multimedia the LOT not even my windows box felt so powerful and that cost me a bloody fortune, oh and dvds that work hahahahahaha.

I am basically building a gateway for the home etc and want to lock an old laptop up in a cupboard somewhere to allow me to control the internet and all the crap that comes theses days to protect innocent surfers, only LINUX will allow me to do this.

so I can fully communicate on the lan and ssh and pass encrypted keys with both machines etc I can do everything but forward internet packets.

DNS type ping fails from the client to the internet but works on the gateway, on the networked laptop I can ping the ppp0 address and it returns, in the P t P address it fails ? I am almost there just not sure whats stopping my packets from getting beyond the modem out to the internet, I have tried to ping the internet and also the ip address for that DNS and both fail just for clarity, i tried to ping the nameservers and they fail too.

So I get as far as the modem if anyone can point me to a topic that covers this I would be grateful. I am on the last issue for my full conversion from windows to redhat linux......

my setup is simple two pcs one is a gateway and both machines are connected via ethernet 100meg via a simple netgear switch, both are redhat 9.0 uname reveals the standard 2.4.20-8 kernel

(yup no more windows from here on, I have even converted my family over to use open source software and we have no issues etc etc......)

Now the two boxes have the correct IP address they can ping with ip and host names,, I have setup iptables manually and the result is below
